Аннотация: Concentration of Cu2+ on carboxylic exchangers of complexing type KB-2T, KB-4, ANKB-35, AMF-2T, AMF-2S from nitric, sulfuric and hydrochloric solutions of different acidity have been studied. The physico-chemical and sorption characteristics of the ion exchangers have been determined. The optimum conditions for the Cu2+ sorption: pH 4,5-5,0, concentration of Cu2+ 0,001-0,5 g/dm3 have been recommended. Ampholyte ion exchangers ANKB-35, AMF-2T and AMF-2S are the most effective for the Cu2+ concentration from natural water and sewage on the base of our researches.
